Off-shell test of the Moscow potential of nucleon-nucleon interaction on the basis of data on the reaction γd → np in the photon-energy region around E γ ≃ 2 GeV, where this reaction is sensitive to quark effects

Abstract

Various pieces of evidence in favor of the Moscow potential of nucleon-nucleon interaction are discussed. The formalism of a relativistic potential model as applied to deuteron photodintegration is expounded. The differential cross section calculated for the reaction γd → np on the basis of the Moscow potential at incident-photon energies Eγ between 1.5 and 2.5 GeV are quite in accord with present-day experimental data, which are also described well in the literature on the basis of the model of quark-gluon strings. Further steps in testing the Moscow potential and microscopically substantiating it on the basis of quark models are indicated.
